Abstract

In this work it is presented a family of six single-phase Current Source Rectifiers (CSR) topologies with asymmetric structures. The topologies present reduced number of active switches and high power factor with low harmonic distortion. Three of the shown structures represent a simplification of full-bridge CSR, replacing two switches from the original topology by two diodes. The other three structures are composed by only one switch, based on single-switch CSR and buck-type CSRs. Details of control strategy and modulation are presented. Experimental results are provided for the full-bridge derived topologies, while simulation results are presented for the other topologies to validate the effective operation of the structures.
